Embodiment 1

[0042] like figure 1 As shown, it is a schematic structural diagram of a display device in the head-up display system provided by Embodiment 1 of the present invention. The head-up display system provided in this embodiment can be installed on the side of the vehicle's windshield located at the driver's cab to provide information or safety warning information to the driver. The head-up display system includes: a display device arranged on the windshield; wherein, the display device includes a transparent display screen 101 and a 3D image generating element 102 ; and the 3D image generating element 102 covers the transparent display screen 101 .

[0043] Specifically, the display device in the head-up display system (HUD) provided by this embodiment is arranged on the windshield of the vehicle. Optionally, the display device covers a part of the windshield to avoid hindering the driver from observing the outside through the windshield. surroundings. Since the display device i...

Embodiment 2

[0054] like Figure 5 As shown, it is a schematic structural diagram of the head-up display system provided by Embodiment 2 of the present invention. On the basis of Embodiment 1, this embodiment also provides a head-up display system that includes a tracking device 52 in addition to a display device 51; the tracking device 52 is used to track the movement of the driver's head or pupils to obtain Monitoring data.

[0055] In an implementation example, the head-up display system further includes a control device 53; the control device 53 is electrically connected to the display device 51 and the tracking device 52; the control device is used to control the image displayed by the display device to follow the The driver's head or pupils move; the control device is also used to adjust the size of the light-transmitting portion according to the monitoring data.

[0056] Specifically, the control device 53 includes a memory, a processor, and a computer program stored in the memory...

Embodiment 3

[0062] like Figure 7 Shown is a schematic diagram of area division of the display device provided by Embodiment 3 of the present invention. On the basis of Embodiment 1 or 2, this embodiment also provides a display device that is divided into multiple display areas in a head-up display system. in,

[0063] The display device includes a first display area 71, a second display area 72 and a third display area 73 distributed on the windshield; the first display area 71 is arranged on the area of ​​the windshield facing the driver; the second display The area 72 and the third display area 73 are respectively arranged on two sides of the first display area 71 .

[0064]Specifically, in order to improve the driver's viewing experience of the images displayed by the display device, the display device may be divided into three display areas according to the distribution positions of the display device on the windshield. The central position facing the driver on the display device c...

Abstract

The invention belongs to the technical field of screen display, and provides a head-up display system and method. The head-up display system comprises a display device arranged on a windshield. The display device comprises a transparent display screen and a 3D image generating component; the 3D image generating component covers the transparent display screen. By covering the transparent display screen with the 3D image generating component, 2D and 3D images can be displayed to a driver at the same time, the parallax error effect is provided for the driver through the 3D images, and therefore the displayed images are more three-dimensional and more clear, and the problem that visual image distortion is generated when the driver views the images displayed on the head-up display can be effectively solved.

Description

technical field [0001] The present invention relates to the technical field of screen display, in particular to a head-up display system and method. Background technique [0002] A head-up display (HUD) is a driving aid that provides information or warnings to the driver through the windshield while driving without requiring the driver to take their eyes off the road ahead of the vehicle. The display image may be given by a display panel mounted directly on the windshield or by an image projector which emits image light which is reflected by the windshield. [0003] However, since the windshield is mostly installed on the car in an inclined state, the driver will produce visual image distortion when viewing the head-up display on the windshield, which will affect the driver's perception of use. Contents of the invention [0004] In view of this, an embodiment of the present invention provides a head-up display system and method to solve the problem of visual image distort...
